ABSTRACT

OBJECTIVE@#To compare the role and importance of fibular fixation in tibiofibular fractures by Meta-analysis.@*METHODS@#The literature related to the comparison of the efficacy of fixation of the fibula with or without fixation on the treatment of tibiofibular fractures was searched through the databases of China Knowledge Network, Wipu, Wanfang, The Cochrane Library, Web of science and Pubmed, and statistical analysis was performed using RevMan 5.3 software. The rates of malrotation, rotational deformity, internal/external deformity, anterior/posterior deformity, non-union, infection, secondary surgery and operative time were compared between the fibula fixation and non-fixation groups.@*RESULTS@#A total of 11 publications were included, six randomised controlled trials and five case-control trials, eight of which were of high quality. A total of 813 cases were included, of which 383 were treated with fibula fixation and 430 with unfixed fibulae.Meta-analysis results showed that fixation of the fibulae in the treatment of tibiofibular fractures reduced the rates of postoperative rotational deformity[RR=0.22, 95%CI(0.10, 0.45), P<0.000 1] and internal/external deformity[RR=0.34, 95%CI(0.14, 0.84), P=0.02] and promoted fracture healing [RR=0.76, 95%CI(0.58, 0.99), P=0.04]. In contrast, the rates of poor reduction [RR=0.48, 95% CI(0.10, 2.33), P=0.36], anterior/posterior deformity[RR=1.50, 95%CI(0.76, 2.96), P=0.24], infection[RR=1.43, 95%CI(0.76, 2.72), P=0.27], secondary surgery[RR=1.32, 95%CI(0.82, 2.11), P=0.25], and operative time[MD=10.21, 95%CI(-17.79, 38.21), P=0.47] were not statistically significant (P>0.05) for comparison.@*CONCLUSION@#Simultaneous fixation of the tibia and fibula is clinically more effective in the treatment of tibiofibular fractures.

ABSTRACT

Physalis Calyx seu Fructus (PCF) is a herb widely used in China for its function of clearing heat and detoxifying, benefitting the pharynx and reducing phlegm, both in health care and in tea drinking. However, the quality of its fruit and calyx is uneven and the storage period is short. Therefore, it is crucial to develop other parts of PCF with longer storage periods and obvious medicinal effects. Firstly, high-performance liquid chromatography was used to develop the fingerprint of different parts of PCF, and various chemometric analyses were conducted to screen out chemical markers. The calyxes of PCF were found to cluster together, distinct from the fruits, roots, stems and leaves. The active components of PCF were concentrated in the persistent calyxes, and flavonoids were mainly found in the persistent calyxes and leaves. Secondly, the extraction of persistent calyxes showed the strongest scavenging ability of DPPH and ABTS. Finally, the important chemical markers were verified by network pharmacological analysis and molecular docking. It provides a reference for the clinical application of PCF, and the obtained chemical markers offer a scientific basis for quality evaluation.

ABSTRACT

OBJECTIVE@#To evaluate the effects of femtosecond laser treated microgrooved surface on microscopic topography, phase transformation, and three-points flexural strength of zirconia, and to provide reference for surface microstructure optimization of zirconia implant.@*METHODS@#According to different surface treatment methods, 57 computer aided design/computer aided manufacture (CAD/CAM) zirconia bars (20.0 mm×4.0 mm×1.4 mm) were evenly divided into three groups: sintered group, no treatment after sintering, taken as control; sandblasted group, sandblasted with 110 μm aluminium oxide (Al2O3) after sintering; microgrooved group, femtosecond laser fabricated microgrooves with 50 μm width, 30 μm depth, and 100 μm pitch. Surface microscopic topography was observed with scanning electron microscope (SEM) and 3D laser microscope. Further, surface roughness in each group and microgroove size were measured. Crystal phase was analyzed with X-ray diffraction. Specimens were subjected to three- points flexural strength test, and Weibull distribution was used to analyze their strength characteristics.@*RESULTS@#SEM showed that sintered surface was flat with clear grain structure; sandblasted surface exihibited bumps and holes with sharp margins and irregular shape; microgrooves were regularly aligned without evident defect, and nano-scale particles were observed on the surface inside of the microgrooves. Ra value of microgrooved group [(9.42±0.28)] μm was significantly higher than that of sandblasted group [(1.04±0.03) μm] and sintered group [(0.60±0.04) μm], and there was statistical difference between sandblasted group and sintered group (P < 0.001). The microgroove size was precise with (49.75±1.24) μm width, (30.85±1.02) μm depth, and (100.58±1.94) μm pitch. Crystal phase analysis showed that monoclinic volume fraction of sandblasted group (18.17%) was much higher than that of sintered group (1.55%), while microgrooved group (2.21%) was similar with sintered group. The flexural strength of sandblasted group (986.22±163.25) MPa had no statistical difference with that of sintered group (946.46±134.15) MPa (P=0.847), but the strength in microgrooved group (547.92±30.89) MPa dropped significantly compared with the other two groups (P < 0.001). Weibull modulus of sintered, sandblasted, microgrooved groups were 7.89, 6.98, and 23.46, respectively.@*CONCLUSION@#Femtosecond laser was able to form micro/nanostructured microgrooves on zirconia surface, which deleteriously affected the flexural strength of zirconia.

ABSTRACT

OBJECTIVES@#To explore the correlation between intestinal microbiota and postmortem interval(PMI) in rats by using 16S rRNA high-throughput sequencing technology.@*METHODS@#Rats were killed by anesthesia and placed at 16 ℃, and DNA was extracted in caecum at 14 time points of 0, 1, 2, 3, 5, 7, 9, 12, 15, 18, 21, 24, 27 and 30 d after death. The 16S rRNA high-throughput sequencing technology was used to detect intestinal microbiota in rat cecal contents, and the results were used to analyze the rat intestinal microbiota diversity and differences.@*RESULTS@#The total number of intestinal microbial communities did not change significantly within 30 days after death, but the diversity showed an upward trend. A total of 119 bacterial communities were significantly changed at 13 time points after death. The models for PMI estimation were established by using partial least squares (PLS) regression at all time points, before 9 days and after 12 days, reaching an R2 of 0.795, 0.767 and 0.445, respectively; and the root mean square errors (RMSEs) were 6.57, 1.96 and 5.37 d, respectively.@*CONCLUSIONS@#Using 16S rRNA high-throughput sequencing technology, the composition and structure of intestinal microbiota changed significantly within 30 d after death. In addition, the established PLS regression model suggested that the PMI was highly correlated with intestinal microbiota composition, showing a certain time series change.

ABSTRACT

Objective To obtain the protein expression profile of rat liver tissue after death by the 2100 bioanalyzer combined with protein chip, and infer the relationship between protein expression profile and postmortem interval. Methods Rats were killed by abdominal anesthesia and placed at 16 ℃. Water-soluble proteins in liver tissues were extracted at 14 time points after death. The expression profile data of proteins with relative molecular weight of 14 000-230 000 were obtained using protein chip, and principal component analysis (PCA), partial least squares-discriminant analysis (PLS-DA) and Fisher discriminant were used to analyze the data. Results According to the changes of protein expression profile, the postmortem interval was divided into group A (0 d), group B (1-9 d), group C (12-30 d) according to the result of PLS-DA. The prediction accuracy of the training set and test set of the model were all 100.0%, and the internal cross-validation of the training set was 100.0% according to Fisher discriminant. The Fisher discriminant model at each time point of group B and C was established to narrow the time window of postmortem interval estimation. The prediction accuracy of the training set and test set were all 100.0%, and the internal cross-validation accuracy of the training set was 100.0% in group B. The prediction accuracy of the training set and test set were respectively 95.2% and 78.6% in group C, and the internal cross-validation of the training set was 88.1%. Conclusion Protein chip detection technology can quickly and easily obtain the expression profile of water-soluble proteins of rat liver tissue with a relative molecular weight of 14 000-230 000 at different time points after death. PLS-DA and Fisher discriminant models are established to classify and predict the postmortem interval, in order to provide new ideas and methods for postmortem interval estimation.

ABSTRACT

Acute myeloid leukemia (AML) is a heterogenic hematological malignancy with pathogenesis that has yet to be elucidated. MicroRNAs (miRNAs) and transcription factors (TFs) are two major regulators of gene expression, which may play important roles in the etiology of AML. However, the global regulation of gene expression in AML, involving miRNAs and TFs, still remains elusive. To characterize the global role of miRNAs and TFs in AML pathogenesis, large scale expression profiling of miRNA and TF was performed using miRNA sequencing and TF array technology, respectively, and validated by qPCR. In the present study, 308 miRNAs and 84 TFs were identified to be differentially expressed (fold-change ≥2.0) in AML samples relative to their controls. After integrating the expression profiling data into bioinformatic analysis, we identified 1,462 miRNA-gene pairs, 982 TF-gene pairs and 296 TF-miRNA pairs. By merging these regulatory relations together, we constructed a comprehensive AML-specific miRNA-TF regulatory network. In this network, we identified 22 hub miRNAs and 11 hub TFs. KEGG pathway analysis showed that the network nodes were significantly enriched in 33 different pathways, of which the AML pathway was the most significant. After analyzing the topology of the subnetwork, we propose that TCF3 was a potential key regulator in this regulatory network. In conclusion, this is the first study perform on global expression profiling of miRNAs and TFs relating to AML. These results may enhance our understanding of the molecular mechanisms underlying AML and provide potential targets for future therapeutics.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the cardioprotective effects of dexrazoxane (DEX) on breast cancer patients who received anthracycline-containing chemotherapy.</p><p><b>METHODS</b>A total of 122 breast cancer patients after operation were randomly divided into two groups: The experimental group of 61 cases treated with EPI plus DEX (DEX:EPI = 10:1) as adjuvant chemotherapy regimen, and the control group of 61 cases treated with EPI but without DEX. All patients received four cycles of adjuvant chemotherapy and their changes of specific cardiac functional status and hematology status before and after chemotherapy, as well as non-cardiac toxicity were observed and analyzed.</p><p><b>RESULTS</b>Brain natriuretic peptide (BNP) before chemotherapy and after four cycles of chemotherapy in the control group was (106.78 ± 4.52)×10(-6) µg/ml and (187.19 ± 8.71)×10(-6) µg/ml, respectively, with a significant difference between them (P < 0.05). It in the experimental group was (102.34 ± 8.76)×10(-6) µg/ml and (105.29 ± 7.21)×10(-6) µg/ml, respectively, without a significant difference (P > 0.05). Cardiac troponin T (cTnT) before chemotherapy and after four cycles of chemotherapy in the control group was (12.55 ± 2.73)×10(-3) µg/ml and ( 31.05 ± 7.10 )×10(-3) µg/ml, respectively, with a significant difference between them (P < 0.05). It in the experimental group was (12.70 ± 2.15)×10(-3) µg/ml and (13.65 ± 7.82)×10(-3) µg/ml, respectively, without a significant difference (P > 0.05). The hart rate (HR) before chemotherapy and after four cycles of chemotherapy in the control group, was 75.32 ± 7.14 bpm and 89.60 ± 9.21 bpm, respectively, with a significant difference (P < 0.05). It in the experimental group was 78.60 ± 6.29 bpm and 83.10 ± 7.56 bpm, respectively, without a significant difference (P > 0.05). The left ventricular ejection fraction (LVEF) before chemotherapy and after four cycles of chemotherapy in the control group was (65.23 ± 7.82)% and (55.21 ± 7.23)%, respectively, with a significant difference between them (P < 0.05). It in the experimental group was (64.12 ± 6.25)% and (59.6 ± 4.72)%, respectively, without a significant difference (P > 0.05). The absolute neutrophil count before chemotherapy and after four cycles of chemotherapy in the control group was (3.95 ± 1.36)×10(9)/L and (3.50 ± 1.52)×10(9)/L, respectively, without a significant difference (P > 0.05). It in the experimental group, was (4.96 ± 1.41)×10(9)/L and (3.10 ± 1.26)×10(9)/L, respectively, with a significant difference (P < 0.05). The incidence of grade I-IV bone marrow suppression in the experimental group was 21.3%, 16.4%, 24.6%, and 4.9%, respectively. It in the control group was 16.4%, 11.5%, 9.8%, and 5.5%, respectively, with a significant difference (P < 0.05).</p><p><b>CONCLUSIONS</b>Cardiac toxicity after anthracycline treatment in breast cancer patients may be significantly reduced by DEX, without increase of non-cardiac and and non-hematologic toxicity. DEX combined with anthracycline increases the risk of bone marrow suppression, therefore, peripheral blood picture should be monitored or routine bone marrow support may be needed.</p>

ABSTRACT

AIM: To study the effect of murine mesenchymal stem cells (MSCs) on the differentiation, maturation and function of allogenetic bone marrow-derived dendritic cells (DCs) and to investigate the mechanism of MSCs displaying immunoregulatory activity. METHODS: BALB/c mice BMCs were isolated and cultured in vitro and then coclutured with C57BL/6 murine bone marrows cells (BMCs) at different ratios in vitro to induce DCs generation. The phenotype of cells was analyzed by flow cytometry. Endocytosis was measured as the cellular uptake of fluorescein isothiocyanate (FITC)-dextram amd was quantified by flow cytometry. The level of IL-12 secretion in the cell culture supernatants was detected by enzyme-linked immunosorbent assay (ELISA). RESULTS: Decreased expression of CD11c, CD14, CD83, CD86 and I-A(b);, down-regulated endocytosis capacity and interleukin-12 (IL-12) secretion of DCs were all observed when MSCs cocultured with BMCs at a higher ratio (1:10). CONCLUSION: Murine MSCs could supress the differentiation and maturation of DCs derived from allogeneic BMCs in vitro.

ABSTRACT

AIM: To analyze the surface markers on peripheral blood dendritic cells (DCs) in SLE patients and explore the relationship between the DCs and pathogenesis of SLE. METHODS: The peripheral blood monouclear cells (PBMCs) were separated by density gradient centrifugation. After culture of 3 hours in tissue culture flask, the suspended cells were removed and GM-CSF, IL-4 and TNF-alpha were used to stimulate the proliferation and maturation of the peripheral blood DCs from normal persons and SLE patients. The surface markers on the DCs were analyzed by flow cytometry and the levels of IL-12 and IFN-alpha in supernatants were measured by ELISA after culture of 9 days. RESULTS: The positive percentages of CD1a, CD11c, CD40, CD83 and CD123 expressed on DCs of SLE patients were (58.88+/-7.64)%, (54.4+/-10.88)%, (37.29+/-8.08)%, (57.76+/-11.54)% and (13.14+/-4.44)%, respectively, whereas those of normal subjects were (47.71+/-4.01)%, (43.12+/-8.82)%, (28.59+/-7.07)%, (48.31+/-8.79)% and (9.85+/-3.97)%, respectively, (P<0.05). But the positive proportion of CD80 expression was (55.16+/-10.12)% in SLE group and (47.95+/-12.21)% in the control group, without significant difference (P>0.05). The level of IL-12 in SLE group was (9.78+/-0.76) ng/L, higher than that in normal group. The level of IFN-alpha in SLE group (2.95+/-0.61) ng/L was not significant difference from that in control group (2.70+/-0.29) ng/L (P>0.05). And there was no significant difference in IL-12 and IFN-alpha levels between non-active and active stages of SLE patients. CONCLUSION: The DCs may be involved in the pathogenetic process of SLE possibly by means of enhancement of antigen presenting function of DCs and secretion of IL-12.

ABSTRACT

<p><b>OBJECTIVE</b>A randomized trial of breast self-examination (BSE) program was carried out to evaluate whether the intensive BSE can reduce the death number of women from breast cancer.</p><p><b>METHODS</b>A total of 266,064 women (age of 30 to 64 years) associated with 519 textile factories in Shanghai had been randomly assigned to a BSE instruction group (132,979 women) or a control group (133,085 women) since 1989. Initial instruction in BSE group included demonstration of proper palpation techniques. It was followed by 2 reinforcement sessions during the subsequent 4 years including video shows, BSE instruction sessions and BSE practice under medical supervision. These activities were continued for 5 years. Attendance at all events was recorded. The cohort was followed through July 2000 for development of breast diseases, and the breast cancer cases were followed up through 2001 for vital status. The data analysis methods used included Kaplan-Meier plots, Log-rank test and Cox modeling.</p><p><b>RESULTS</b>Among women under instruction, 864 breast cancers were detected and 133 breast cancer deaths occurred, and 896 breast cancers were detected and 130 deaths recorded in the control group. The tumor size (P = 0.07), TNM stage (P = 0.39) and cumulative breast cancer mortality rate (P = 0.72) were not significantly different between the 2 groups. However, more and smaller fibroadenomas were detected in the instruction group than in the control group (P < 0.01).</p><p><b>CONCLUSION</b>Intensive instruction in BSE can not reduce mortality rate of breast cancer, but more and smaller benign breast lumps can be detected.</p>

ABSTRACT

BACKGROUND & OBJECTIVE: P27 protein and cyclin E were negative cell cycle regulators. Until the present, the influence of P27 protein and cyclin E on progression of colon cancer was unclear. The aim of this study was to observe the expression features of P27 protein and cyclin E in the tissues of colon neoplasms, and to investigate the relationship between colon neoplasms and tumor special growth factor (TSGF). METHODS: Sixty-nine cases of samples included 23 normal tissues, 28 colon polyps (13 inflammatory polyps and 15 adenomatous polyps), and 18 colon carcinomas. The location and expression of P27 protein and cyclin E were determined using immunohistochemical method in all samples. These samples were diagnosed using formal pathological techniques simultaneously; the relationship between colon neoplasms and TSGF was also investigated. RESULTS: The positive signal of P27 and cyclin E was found mainly in the cytoplasm and extracellular matrix of normal colon tissues, inflammatory polyps, and adenomatous polyps. Less amount of positive expression product of P27 protein and cyclin E was observed in colon carcinoma cells; and the positive signal was only located in the cytoplasm of gland-like cells. The content of TSGF in colon carcinoma tissues was significantly higher than that in normal tissues (117.3+/-57.02 versus 64.16+/-27.5,P< 0.01), but there was no significant difference between colon carcinoma tissues and inflammatory polyp tissues (117.3+/-57.02 versus 92.5+/-47.9,P >0.05). CONCLUSION: P27 protein and cyclin E participate in the adjustment process of colon neoplasm occurrence and progression. The reduced expression of P27 protein and cyclin E may indicate the possibility of colon carcinoma.
